Purporting to be a tribute to the great scientist Charles Darwin, this
piece of work is really a vehicle for tooting the string theorist's
horn by proposing a mind-bogglingly fatuous analogy between Darwin's
Evolution and String "Cosmology".
Here is a sample: "Let us begin with the DNA of the universe. ...
String theory is the key. It supposes that at extremely small
distances space is a complicated higher-dimensional manifold with
many ... tiny "extra" dimensions ... ; it is composed of "Tinkertoy"
elements called fluxes, branes, moduli, orientfolds (and more) all
arranged on a tiny knot of higher-dimensional space called a Calabi-
Yau manifold. The Calabi-Yau manifold is like the basic spine of the
DNA molecule, ... " And so on in relentless intoxicated delusion.
Do not be alarmed - the problem is not with your eyes or brain [at
least I hope not].
Did the editors of Physics World have any doubts about this piece of
whatever, or is anything the "king of string" writes absolutely
correct by definition?

This is New Age babble that is completely untestable in any practical
manner.
This is not science.
